The rate of effusion of ammonia (NH₃) in the same apparatus is 63.3 cm/min
<h3>Graham's law of diffusion </h3>
This states that the rate of diffusion of a gas is inversely proportional to the square root of the molar mass i.e
R ∝ 1/ √M
R₁/R₂ = √(M₂/M₁)
<h3>How to determine the rate of ammonia (NH₃) </h3>
- Rate of HCl (R₁) = 43.2 cm/min
- Molar mass of HCl (M₁) = 1 + 35.5 = 36.5 g/mol
- Molar mass of NH₃ (M₂) = 14 + (3×1) = 17 g/mol
R₁/R₂ = √(M₂/M₁)
43.2 / R₂ = √(17 / 36.5)
Cross multiply
43.2 = R₂ × √(17 / 36.5)
Divide both side by √(17 / 36.5)
R₂ = 43.2 / √(17 / 36.5)
R₂ = 63.3 cm/min
Thus, the rate of effusion of ammonia is 63.3 cm/min

Explanation:
Answer:
λ = 2.9 × 10⁻⁵ m
General Formulas and Concepts:
c = λν
- C = Speed of Light (3 × 10⁸ m/s)
- ν = frequency (Hz or 1/s⁻¹)
Explanation:
<u>Step 1: Define</u>
ν = 10.4 × 10¹² Hz
<u>Step 2: Solve for λ</u>
- Substitute: 3.0 × 10⁸ = λ(10.4 × 10¹² Hz)
- Divide both sides by ν: 0.000029 = λ
- Rewrite: λ = 2.9 × 10⁻⁵ m
<u>Step 3: Check</u>
